Take it out the top.

Quite right. Just pull the head off and the rod will allow it to move forward enough to push the pin out.


Here below are a couple pictures to guide you.
I will also mention that since the trimming of one winding off the governor spring in the finial it is better to replace it with a softer spring.


Have fun!

To remove the head to get at your piston....
First remove the bolt with the blue arrow pointed at it.

Can't get the M92 Piston out? Its hitting the left side. Not sure how they managed to get it in there?
There's way different clearance between the axle support on the left to the right side.
